View and Save buttons disappeared

Hi !

I'd installed drupal 5.7 and have created a content type with cck fields. When i tryed to add content i noted that there's no view and save buttons. What happening ?

I have installed the following modules: cck, cck_blocks, conditional_fields, contemplate, emfield, fivestar, fixeddatadropdown, imagefield, link, votiongapi and wizard.

I give access to create, access an edit content to my personal content type and to page and story content types. The strange thing is that the content type fields appear for all content types, but the buttons to save and view content does'nt.

Any idea ?

Thanks.
